Question

In quadrilateral PQRS, ∠Q = 90° = ∠S, SP = 15 cm, PQ = 7 cm, QR = 24 cm.

The length of PR is ______.

विकल्प

• 28 cm

• 26 cm

• 25 cm

• 30 cm

Answer 1

The length of PR is 25 cm.

Explanation:

By Pythagoras theorem,

PR² = PQ² + QR²

= 7² + 24²

= 49 + 576

= 625

PR = `sqrt(625)`

= 25 cm
